NAME

SYNOPSIS

DESCRIPTION

This module saves the last passwords for each user in order to force password change history and keep the user from alternating between the same password too frequently.

This module does not work together with kerberos. In general, it does not make much sense to use this module in conjunction with NIS or LDAP, since the old passwords are stored on the local machine and are not available on another machine for password history checking.

OPTIONS

When password changing enforce the module to use the new password provided by a previously stacked
password
module (this is used in the example of the stacking of the
pam_cracklib
module documented below).

enforce_for_root

If this option is set, the check is enforced for root, too.

remember=N

The last
N
passwords for each user are saved in
/etc/security/opasswd. The default is
10.

retry=N

Prompt user at most
N
times before returning with error. The default is
1.
